App-download QR code
TL;DR — An app-download QR detects the visitor's device (iOS or Android) and redirects to the right store. One printed QR — both stores covered.
How smart app-redirect works
Static app QRs encode either an App Store URL or a Play Store URL — but not both, since a static QR is one URL. Anyone on the wrong platform gets a confusing error page.
Dynamic app QRs solve this: the QR encodes a short link (qrshop.io/s/abc) which hits our redirect server. We sniff the User-Agent header for iOS or Android and 302 to the right store. One QR, every device, smart routing.
When to use it
Anywhere your app is the destination:
- Conference / trade-show booths promoting your app
- TV / OOH campaigns where you don't know the viewer's device
- In-store displays for native apps (e.g. retail loyalty)
- Press releases and media kits where journalists scan
- Product packaging that should drive app installs
Frequently asked
Can the app QR open the app if it's already installed?
Yes — with deep links. Configure your app's universal-link / app-link domain, point the QR at a deep link URL, and installed apps open directly. Uninstalled users still get the right store.
Can I track install conversions from the QR?
Yes — pair the dynamic QR with a tracking URL like Branch, AppsFlyer, or Adjust. Install attribution flows through their SDK.
